EXIF data (was: RE: [Leica] M8 trials and tribulations?)

When you buy a frozen turkey or chicken or goose, it has been plucked and 
cleaned. Normally the "giblets" -- various organs such as heart and liver 
and kidneys, and the neck -- are wrapped in paper and placed inside.

Not very many people want the giblets. Usually they are just discarded. But 
if you are one of the people who does want them, it's very hard to go back 
to the slaughterhouse to find the giblets that came from your frozen bird.

So poultry processors pack the giblets inside each frozen turkey and chicken 
and goose, simply because they might possibly be needed and it is not a huge 
amount of work.

The EXIF data in a digital image is just like the giblets from a frozen 
turkey: you probably don't want it, but if you do, there it is, and it's 
easy to discard it if you don't want it.
